Paraphenylenediamine (PPD) is a common ingredient in many hair dyes and can cause allergic reactions in some individuals, ranging from mild irritation to severe dermatitis. While it is generally considered safe for use in regulated amounts, frequent exposure may increase the risk of sensitization. It's essential for consumers to perform patch tests before using products containing PPD and to be aware of any personal sensitivities. If you experience adverse reactions, it’s advisable to discontinue use and consult a healthcare professional.
